AAA Predicts Favorable Fuel Prices for Fall

OMAHA, NE, (August 29, 2018) – AAA forecasts the national average pump price will drop 14-cents to $2.70 or below this fall, saving motorists more than 25-cents per gallon compared to prices reported back in May when unleaded climbed to a yearly high of $2.97 a gallon.  Currently, the national average is $2.835 a gallon for unleaded fuel.   
“Labor Day signals the end of the summer travel season and the beginning of an autumn trend that normally leads to lower gas prices,” said Rose White, spokesperson for AAA-The Auto Club Group.  “In September, gasoline demand drops and refiners switch to a cheaper-to-produce winter-blend fuel, putting downward pressure on prices at the pump. However, several factors can reverse this forecast including crude oil price hikes, geopolitical tensions, and the threat of a hurricane on oil operations.”

Gasoline prices for 2018 have been more expensive than 2017.  AAA reports that the 2018 year-to-date national gas price average of $2.73 a gallon for unleaded fuel is 41-cents more than the 2017 year-to date average of $2.32 a gallon. 
When comparing 2018 against 2017, Nebraska and Iowa report the smallest year-over-year variance in fuel prices among all 50 states.  AAA’s summary shows Nebraska with the lowest price variance with fuel averaging 35 cents more than last year.  Nebraska’s average was $2.30 a gallon in 2017, compared to $2.65 for 2018.  Iowa reports the second lowest year-over-year price variance of 36 cents per gallon. Iowa’s average was $2.28 in 2017, compared to $2.64 for 2018.

What Will Push Pump Prices Down this fall?
Part of the anticipated drop in fall pump prices is due to the switchover to winter-blend gasoline in mid-September. The difference between summer- and winter-blend gasolines involves the Reid Vapor Pressure (RVP) of the fuel. RVP is a measure of how easily the fuel evaporates at a given temperature. The more volatile a gasoline (higher RVP), the easier it evaporates. Winter-blend fuel, which is cheaper to produce, has a higher RVP because the fuel must be able to evaporate at low temperatures for the engine to operate properly, especially when the engine is cold.
In addition, the arrival of fall historically means a drop in consumer gasoline demand as fewer Americans take extended road trips, compared to the summer.
